Hi, I'm sorry to ask this dumb question, but I don't manage to enable the MindTheDark template. I have Dokuwiki 2020-07-29 "Hogfather" (for now only a local installation) and used the standard dokuwiki template. I now want to use a different template, the MindTheDark template. I installed it via the extension manager, but it is greyed out. I then went to the configuration manager and selected the template MindtheDark in the "basic" section. However, I cannot save this configuration. It always jumps back to the standard template. I checked, the MindtheDark folder is in the lib/tpl folder. I would be grateful for a tip.
